THOMAS FEARON, OF YONKERS, NEW YORK.

STEAM-HEATER.

SPECIFICATION forming part of Letters Patent No. 484,787, dated October25, 1892. Application filed May 1, 1891. Serial No. 391,215. (No model)To all whom it may concern.-

Be it known that I, THOMAS FEARON, of Yonkers, in the county ofWestchester, in the State of New York, have invented new and usefulImprovements in Steam Heaters, of which the following, taken inconnection with the accompanying drawings, is a full, clear, and exactdescription.

My invention relates to an improved steamheater, and has for its objectthe production of a durable, simple, and highly-efficient constructionpossessing a great amount of heating-surface for producing a maximumdegree of steam with a minimum amount of fuel, and capable of beingreadily repaired without the exercise of great skill or ingenuity andwithout preventing the operation of the entire boiler while a portion isbeing repaired.

To this end the invention consists, essentially, in a pair ofsteam-drums, a rectangular water-containing base, a series of uprightheads or manifolds arranged alternately in two rows at the center of theheater and having their upper extremity connected to one of thesteam-drums and their lower end to the water-containing base,heating-sections projecting from each of the outer faces of said headsand composed of a series of U- shaped tubes or pipes arranged one withinthe other with their opposite ends connected to the heads or manifolds.

The invention furthermore consists in a superheater depending from theend of the drums and mounted between the top and bottom legs of theinner U shaped heating-tubes, in deflecting-plates also mounted betweenthe opposite legs of said pipes for passing the heat around thesuperheater, and in the detail construction and arrangement of theparts, all as hereinafter more particularly described, and pointed outin the claims.

In describing this invention reference is had to the accompanyingdrawings, forming a part of this specification, in which like lettersindicate corresponding parts in all the views.

Figures 1 and 2 represent, respectively, elevation and top plan views ofmy improved heater. Fig. 3 is an elevation taken at right angles toFig. 1. Figs. 4 and 5 are horizontal sectional views taken on therespective sectional lines ax and y y, Fig. 1. Fig. 6 is an enlargedhorizontal sectional view of a portion of the heads or manifolds and theheating-pipes projecting therefrom, illustrating particularly theconstruction and arrangement of these parts and the plug for permittingexpansion of the tubes; and Fig. 7 is a horizontal sectional view of amodified form of heater.

It is well known that the aim of manufacturers of boilers designed foruse in steamlaunches, &c., is to make the boiler as low down as possibleand at the same time provide a great amount of heating-surface, and soconstruct the boiler that it may be readily repaired at a minimumexpense andby an or dinary pipe-fitter, and be perfectly free to ex pandand contract in operation.

My invention is designed to meet the abovementioned requirements and tofurnish a maximum amount of steam with a minimum amount of occupiedspace for the heater and required fuel.

A represents the water-containing base consistin g, preferably, of aseries of pipes at a a a, joined by elbows a. This base may, however, becomposed of a single casting, if desired.

B represents the steam-d ru m, of which there are preferably two,arranged lengthwise from front to back of the heater and slightlyseparated from each other, with their opposite ends connected to thebase A by pipes B for passing to the water-containing shell any waterwhich may accumulate in the drum B.

0 represents the upright or vertical hotwater head or manifold, arrangedat the center of the heater for supporting the projecting heating-pipesD. These heads are preferably arranged in two rows and alternate witheach other, as best seen at Fig. 6. The upper end of each head 0 isconnected by a U-shaped tube or pipe 0 to the top portion of thefarthest drum, as best seen at Figs. 1 and 2, and the bottom portion isconnected by an L-shaped tube 0 to the adjacent pipe a, whereby thesteam passes to the steam-drum and the sediment to thecold-water-containing base A. It will be noted upon reference to thedrawings that the connecting-pipes 0 have one or more bends and extendby and ICO laterally overlap each other. The heatingsections Dpreferably project from the outer face of the manifolds or heads Oto theouter face of the grate, (not shown,) and are arranged in the form of anest, consisting of a series of U-shaped tubes 01 d d (1, having theiropposite ends secured to or communicating with the heads 0 and theircentral portion projecting outwardly to the extreme wall of the heater.As best seen in Fig. 6, the heads are cylindrical and are provided witha nipple or plug 0' for closing an opening 0 arranged in the wallopposite to the entranceopening for permittingthe entrance of anexpanding-tool adapted to expand the tube for holding the same firmly inposition. As also seen in Fig. 6, this arrangement enables the tubes tobe mounted extremely close to each other, since the projecting portionof the nipple projects into the space between the adjacent walls of theheads. It is evident, however, that instead of composing theheatingsections D of tubing they may be composed of piping, in whichcase the plugs 0' may be dispensed with. In case one of the sectionsneeds repair, it may be readily removed by removing the pipes c and O,and the holes for said pipes may be then plugged, and the entire heatermaybe operated without the injured heating-section.

E represents the superheater, having one ende depending from the drum Band the other formed with a series of coils and mounted between theopposite legs of the central heating-pipe d, as best seen at Figs. 1, 2,3, and 5.

For the purpose of rendering the contact of the heat with thesuper-heater more positive and certain I provideaseries of bentdeflecting or baffle plates E, also mounted between the opposite legs ofthe inner heating-tubes d and bent around the separate legs of eachcoil.

Upon reference to the foregoing description it is evident that thepeculiar arrangement of heating-coils aflords an unusual degree ofheating-surface in proportion to the space occupied, and it is thereforeevident that the heater or boiler may be correspondingly lowered inproportion to its capacity. Moreover, the steam is brought to anextremely-dry condition, being passed from the upper end of the drum 0to thehorizontal steam-drums B, from which any water is constantly drawnby the pipes B and thence through the superheater before its passage tothe engine.

The heater may be readily repaired. Its construction is simple,efficient, and durable, and permits a great amount of expansion andcontraction of the parts. The water preferably enters into the lowershell A through the pipe F, and the sediment which accumulates withinthe lower shell A may be blown ed by means of a pipe G, extending fromsaid shell.

The L- shaped pipes 0 form the fire-box, and for the purpose of myinvention I have deemed it unnecessary to illustrate here thefire-grate, the fire-brick, which may be placed on the outside of thepipes O, or the outer shell, all of which parts may be of the ordinaryor any special construction.

At Fig. 7 I have shown a modified form of heater, in which the heads ormanifolds are rectangular in cross-section and consists of separatehalves (3 0 adapted to be drawn together by bolts 0 These heads areillustrated as slightly separated to allow for expansion, andcontraction, but, if desired, may be in direct contact with each other.Projecting from the outer walls of said heads or manifolds are curvedpipes arranged disposed in two rows, with the pipes alternately arrangedwith each other and with the outer ends of each pair curved one over theother and considerably separated in order that the entire space may bebroken up and the products of combustion compelled to impart their heatto the pipes without the presence of any space of easier passage.

The operation of my nvention willbereadily perceived from the foregoingdescription and upon reference to the drawings, and it is evident thatconsiderable change may be made in the detail construction andarrangement of the parts without departing from the spirit of myinvention.
